Step-by-step explanation:

To simplify this, we must first set the fractions' denominators to match.

We can do this by multiplying each fraction by the other's denominator, as follows:

Then, you can subtract them, keeping the denominators the same:

Them, simplify the equation:

This is the most simplified form of this expression, as the quadratic expression in the numerator cannot be factored.

step-by-step explanation:

step-by-step explanation:
